i have same issue of this post but i'm using google spreadsheet. though it's not considered "programming" topic, regex syntax same. i need extract text between 2 tags. eg: start sample text end when apply regex syntax works: "start(.*)end" but if sample text contains new line not. hints? if want rid off new line character, 1 solution replace new line character "", e.g: =regexextract(regexreplace(a1, "\n", ""), "start (.+) end") if want keep new line character, try: =regexextract(a1, "start (\w+\n\w+) end") alternatively if want solution works strings , without new line character, try: =regexextract(a1, "start (\w+|\w+\n\w+) end")

gurus, i have list looks following : [u'test1', u'test2', '', ''] i trying find way replace character u before 'test1' , 'test2' none ''. after replacing like: ['test1','test2', '', ''] initially had list following: [u'test1\n', u'test2\r\n', '', ''] this reduce using following: row_val = [w.replace('\n', '') w in row_val] row_val = [w.replace('\r', '') w in row_val] let me know there way perform same without iterating through each string. the u not string character, telling unicode object rather str object. you can do: row_val = [str(w) w in row_val]

i creating todo list kind of app. app 7 screens set target , complete that. screenshot here . while coding realized there lots of redundancy in code, like: 1> 7 day of week need create 7 fragments 7 fragments need perform same operations. can w/o 7 fragments? 2> there 15 checkboxes , 15 textview all-i need reference, perform onclick operations separately on each 1 , settext , gettext on each user try modify them. here 1 of textview modify code: ptext2 = (textview) view.findviewbyid(r.id.p_textview2); ptext2.setonlongclicklistener(new view.onlongclicklistener() { @override public boolean onlongclick(view view) { alertdialog.builder alertdialog = new alertdialog.builder(getactivity()); alertdialog.settitle("target"); alertdialog.setmessage("set target"); final edittext input = new edittext(getactivity()); alertdialog.setview(input);

this looks trivial query can't seem make work.. trying instance object has locationname = "nyc" , groupname = "adults". trying query using code found on parse documentation: var groupquery = new parse.query("mytable"); groupquery.equalto("group", groupname); var locationquery = new parse.query("mytable"); locationquery.equalto("location", locationname); var mainquery = parse.query.or(locationquery, groupquery); but fail because using parse.query.or instead should have been parse.query.and which, reason doesn't exist... there alternative way it, reason cannot find on documentation.. cheers parse queries use , default, why there parse.query.or(). want can achieved way : var mainquery = new parse.query("mytable"); mainquery.equalto("group", groupname); mainquery.equalto("location", locationname);

i have web api controller looking similar this: public void post([frombody]dynamic postdata) { foreach (var row in postdata) { var email = row.email.value; // ok var eventtype = row.event.value; // cannot use because "event" reserved .net, c# or whatever } } i'm getting json external system contains "event" property (outside of control), i'm unable retrieve. i've tried dozens of workaround, none of them seemed work in scenario. there easy way of retrieving it. the best bet had using reflection like: row.gettype().getproperty("event").getvalue(row, null); but didn't work had expected. there else can try? solution use "@" like: row.@event.value

i'm embarrassed wield weak math skills, , proud computer science major. i'm in class, , it's overwhelming. part of homework assignment, however, can't continue on until understand section. in class struggling on writing method complete assignment. emailed professor, asking clarification on how method should written. he said supposed store 8-bit numerator , 8-bit denominator... however... not understand numerator , denominator is. can please explain me? this part of response got professor: "[you're] supposed encode coefficients a, b, , c chromosome [ chromosome our interface, chromosome chrome our object]. a, b, , c numbers can fractional. must store 8-bit numerator , 8-bit denominator. a, b, , c can positive or negative." after this, we're supposed map a, b, , c binary string create new chromosome object. how translating this: a, b, , c going doubles (at least) holding decimal value. can't implement until know 8-bit numer

i new zedboard. have zedboard running ubuntu image. trying write driver run oled on board. on board start-up oled on board shows display(xilinx logo), therefore assuming has driver. have following questions: a) how oled in zedboard internally connected, through spi, gpios or pl. if it's through spi/gpios pins? b) tutorial or documentation can follow create userspace drivers using spi/gpio oled in zedboard? c) have redhat desktop, there sdk can use develop userspace drivers zedboard redhat desktop. i have seen lot of materials on zedboard none of them talks how oled internally connected. in 1 document shows it's connected pl. if that's case how can write userspace drivers using pl on zedboard? coding using c. appreciate , in advance! a) how oled in zedboard internally connected, through spi, gpios or pl. if it's through spi/gpios pins? first or second result web search "zedboard oled pdf" - http://zedboard.org/sites/default/files/z
